No. 547,231 Claims priority, application Japan, Nov. 24, 1965, 40/72,?)21 4 Claims. (Cl. 1l2-412) ABSTRACT OF THE DISCLOSURE A tufted cord rug made up of a plurality of lengths of core material. The core material has a plurality of wrapping or covering materials wrapped spirally around the lengths of core material with the materials around at least the outermost of said lengths at the edge of the rug extending outwardly from the core material as looped tufts forming a fringe for the rug. A plurality of bracing threads or yarns is interlaced at and around the root portions of the tufts where the tufts depart from the core, the bracing threads or yarns being interwoven with the tufted threads at predetermined regular intervals.

This invention relates to improvements in cord for rugs, composed of braids or cords sewn up into a circinate, juxtaposed or other desired shape, and having fringe around the outer periphery and/or having pile on the surface of the rug.

As the conventional means for forming fringe around the outer periphery of a so-called braided rug, tubular braided rug or wrap-a-round rug, there has heretofore been proposed and practiced a means of sewing on one side of the outer periphery of a rug a separately-prepared fringe which is comprised of fringe-forming yarns or threads woven or seamed otherwise to the base material for the fringe.

However, this conventional means is quite disadvantageous in that in the first place it requires sewing a separately-prepared fringe on one side of the outer periphery of a rug, after the latter has been sewn up, which enevitably makes for difliculty in color matching between the rug proper and the fringe because of the separate preparation. In the second place the fringe tends to disengage from the rug proper, when the sewing is inadequate or the sewing threads used therefor are frictionally damaged or broken.

Moreover, in the described conventional construction, the sewn-on base of the separately-prepared fringe always appears on one side of the outer periphery of a rug proper. It therefore detracts considerably from the otherwise fine appearance on that side of the rug and, thus the rug is not suitable for the reversible use. Apart from the above, there has seldom been proposed or practiced the use of a pile construction in the production of braided rugs or the like rugs.

The primary object of this invention is to provide a tufted cord for rugs at low cost, which is capable of forming a looped form or a cut form of fringe around the outer periphery of a rug proper in an easily feasible manner so as to greatly improve the external appearance of the rug, and which is also capable of forming a looped form or a out form of pile on the surface of a rug so as to give an unusual appearance of the rug and a thick feeling to the hands and an attractive look to the eyes.

Another important object of this invention is to provide a tufted cord for rugs, which will hold the tufts firmly without any other reinforcement at the root portions where the said tufts are rooted, and which accordingly will integrally retain its pre-patterned shape and will give an elegant external appearance to the rugs.

According to the present invention, the tufted cord for rugs comprises at least one core material, and a plurality of wrapping or covering materials wrapped spirally around the said core material and extending laterally of the said core material for a predetermined length to constitute a number of looped tufts on one side of the cord. A plurality of bracing threads or yarns are interlaced at and along the root portions of the looped tufts in such a manner that the said threads or yarns extend over and under the said tufts, at a predetermined regular interval, to interlock the same at least one at a time. The looped tufts may be cut at the outermost ends of each loop.

Inasmuch as the tufts of the cord for rugs according to the present invention are constituted by the plurality of wrapping or covering materials for the core material, and are interlocked at their root portions with the plurality of bracing threads or yarns in the way described hereinabove that they, are fast on the cord, they do not disintegrate. Therefore they need not be seamed or stitched, and consequently this tufted cord for rugs has an advantage in that a high productivity can economically be obtained with facility. Further since the said tufted cord is evenly uniform on both sides, the rug fringed with the said tufted cord is more trim and natural than the conventional rug with a separately-prepared fringe sewn on one side of the same.

It has a further advantage in that a complex and elegant embroidered pattern can be formed at the outer periphery of a rug fringed with this tufted cord for rugs where the plurality of the bracing threads are interlaced at and along the root portions of the tufts to interlock the said tufts fast at their root portions. The said rug can be made still more colorful by the employment of multi-colors for the plurality of the bracing threads or yarns.

Furthermore, since the tufts are in fact the extension of the plurality of the wrapping or covering materials, the root portions wherein they are rooted look perfectly trim and natural. Also by the use of multi-colors for the plurality of the wrapping or covering materials, they may be made into a beautiful cord for rugs which has elegantly multi-colored tufts.

The tufted cord for rugs of the present invention is still further advantageous and useful in that not only the plurality of the wrapping or covering materials but also the bracing threads or yarns can be multi-colored at the same time, which will make the said cord have elegantly colored tufts matched with the colorfully embroidered pattern at their root portions, and which effect will give a dazzling gorgeousness to the appearance of the said cord and will substantially increase the commercial value of same.

Having such advantageous features, as described above, the tufted cord for rugs of the present invention may conveniently be sewn to the outer periphery of a rug proper with the tufted portion laid horizontally and outwardly from the rug proper to make a fringed rug, both sides of which may be attractive and reversibly used. In another application, it may also be made into a pile rug which is richly thick and luxurious when the tufted cords are sewn in parallel with the tuft-bearing side held upward. This feature contributes greatly to the marketability of the rugs which have conventionally been fiat and rather monotonous.

These and other objects will be better understood from the following specification and attached drawings, in which:

FIGURE 1 is a plan view of an example of the tufted cord for rugs according to the invention, with part thereof broken away;

FIGURE 2 is a plan view of another example of the tufted cord for rugs according to the invention, in which the outermost ends of the looped tufts as shown in FIGURE 1 are cut;

FIGURE 3 is an expanded view showing the fundamental construction of the tufted cord for rugs according to the invention;

FIGURES 4 through 6 respectively are schematic views illustrating the modes of use of the tufted cord for rugs according to the invention, in which FIGURE 4 is a schematic cross-sectional view showing the tufted cord for rugs shown in FIGURE 2 sewn to the outer periphery of a rug proper with its tufts laid horizontally to provide fringe;

FIGURE 5 is a schematic cross-sectional view of a pile rug in which the tufted cords for rugs shown in FIGURE 2 are sewn up side by side with their tufts held upward to provide pile; and

FIGURE 6 is a schematic plan view illustrating a rug with the tufted cord of the invention sewn to the outer periphery of a circinate rug in such a manner that its tufts extend horizontally and outwardly from the said periphery to form fringe.

Referring more particularly to the drawings, the tufted cord for rugs as shown in FIGURE 1 comprises a heavy or thick core material 1, which is in the form of a cord, and six fine wrapping or covering materials 2 wrapped spirally around the core material 1 and extending outwardly from the core material to form a number of looped tufts 4 along one side of the cord. Said tufts have interlaced at and along their root portions four bracing threads or yarns 3 with the said threads or yarns 3 woven over and under the root portions of the said tufts alternately to interlock two each in sequence of the said tufts.

In this embodiment, the looped tufts 4 formed from the extended wrapping or covering materials 2 which wrap around the core material 1 are so tightly interlocked by four bracing threads or yarns 3 at and along their root portions that the looped tufts 4 will not distintegrate. As a result it is not necessary that the tufts be sewn by sewing machine or otherwise secured to the core.

FIGURE 2 shows a further version of the embodiment of the tufted cord for rugs according to the invention. In this mode of the embodiment, the resulting rug will have a more trim and attractive fringe or pile, as the case may -.be, than the foregoing example shown in FIG- URE 1, as the tufts 4 of the tufted cord for rugs of the present invention are cut at their outermost ends to form cut tufts 4. In all other respects they are entirely identical to those of the embodiment illustrated in FIG- URE 1.

Regarding the further advantages of the tufted cord for rugs of the present invention as shown in FIGURE 2, it may be sewn, with its out tufts 4' laid horizontally, to the outer periphery of a rug proper R, as illustrated in FIGURES 4 and 6. There is thus produced an attractive reversible rug with a cut fringe, having a specific embroidered pattern at the Outer periphery of the said rug proper where the bracing threads or yarns are evenly and uniformly interlaced at and along the root portions of the fringe tufts to interlock the said tufts fast thereto. Therefore when compared with a rug having attached thereto a separately-prepared sewn-on fringe, the appearance of the fringed rug made up with the present tufted cord for rugs will be greatly improved. It will have no unsightly seams or irregular stitches of the sewing threads, and since the appearance of the rug on both sides is identical, the rug will be reversible.

And alternatively, the present tufted cord for rugs may be sewn up into a circinate, juxtaposed or other desired shape with the cut tufts 4 held upward, as ilillustrated in FIGURE 5. There is thereby obtained a beautiful rug with pile which will give an unusual apparance to the rug and a thick feeling to the hands and an attractive appearance to the eyes. Further if the tufted cord for rugs of the present invention which has comparatively longer tufts is used, at a suitable interval such as every other, every two or every three rows of the conventional braids or cords, with said tufts held up ward, a shaggy pile rug can be obtained.

The materials and other features of the tufted cord for rugs according to the invention will hereinafter be described.

For the core material there may be used a long flexible soft cord of long or short fibers, a synthetic resin tube, cord-like sponge rubber, etc.

The wrapping or covering materials are preferably yarn of wool, cotton or other fibers which may be easily colored or dyed and which feel soft. The bracing threads or yarns can 'be the same materials as the Wrapping or covering materials. However, finer and stronger threads or yarns are better suited for the firm and integral bracing of the tufts, for the decorative effect of the embroidered pattern with the bracing threads or yarns and for economical purposes.

Further, the number of the wrapping or covering ma terials and that of the bracing threads to be used and the intervals the former is interwoven with the latter may all be determined at will. For example, twenty wrapping or covering materials may be interlocked with twenty bracing threads in such a way that the said wrapping materials are interwoven; and with the bracing threads five at a time. Alternatively, as shown in FIGURES 1 and 2, six wrapping or covering material can be interlocked with four bracing threads in such a manner that the wrapping or covering materials are with the bracing threads two at a time. FIGURE 3 shows an expanded view of one example wherein six wrapping or covering materials, a, b, c, d, e, f, are interlocked with two bracing threads, g, h, in such a manner that each one of the wrapping materials is alternately interwoven with the two bracing threads, g, h. It must be noted that the number of wrapping or covering materials and the number of bracing threads or yarns and also of the interweaving intervals between the two are not limited but can be determined at will, as long as the tufts formed along the cord can be interlocked evenly and made fast.

While the invention has been described with reference to the principal embodiments, those are only for the purpose of illustration and the invention is not limited thereto, and many changes and modifications other than those described above may be made by a person skilled in the art. It is to be understood therefore that it is intended to cover all such changes and modifications so long as they do not depart from the scope of the invention as defined in the appended claims.
